This article examines the impact of nanotechnology on the development of flame retardant materials in the field of construction. The general provisions of nanotechnology and nanocomposites, their characteristics and classification are described. Examples of the use of nanotechnology to create fire-resistant materials and their direct application in construction are presented. The main problems of nanocomposites are presented, the solution of which will allow to bring passive fire protection of buildings and structures to a new level.

Keywords: fire protection, fire-resistant material, nanotechnology, nanocomposite, composite material, composite, polymer, material
